Clarkson congratulated the couple with her own tweet, which led to a flurry of well wishes from other fans. There was also at least one dissenter, who used a derogatory term and called the same-sex marriage "a sin any way you cut it."

"But (you) know what, truth does, & the truth is that God is Love, & Love shared between two people should be praised not condemned in my personal opinion. I love (you too) although we see the world/love differently."

Kiana Clark quickly responded to this tweet, thanking Clarkson for "standing up for 'us' and more importantly, for what you believe in."

Clarkson has frequently expressed her support for the LGBTQ community, penning a "love letter" in Billboard magazine for Gay Pride Month in 2017.

"It should be a no-brainer to lift, and support everyone, in every community, and encourage people rather than fear or judge what is different from themselves," she wrote.
